Signal output from the IFC-D/P module
Commands from the distant station are output through relays K1...K4 in the case of module IFC-D
and relays K13...K16 in the case of module IFC-P. Compared with module IFC-P the relays of
module IFC-D are slower but they can switch more power. With module IFC-D power circuit break-
ers can be operated directly.
